BACKGROUND

Generally, vehicles include systems with one or more headlights that illuminate a region in front of the vehicle to provide a visible field of view for a driver of the vehicle. In some configurations, conventional headlight systems may include two illumination schemes, namely, a high beam and a low beam. The high beam may illuminate a region above a visual horizontal axis of the driver, and is typically only utilized during conditions of significantly low visibility (e.g., at night on an unlit road). The low beam may illuminate a region below the visual horizontal axis of the driver, and is typically used during normal low light conditions (e.g., at night on a lit road).

The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the use the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. Furthermore, the use of “right”, “left”, “front”, “back”, “upper”, “lower”, “above”, “below”, “top”, or “bottom” and variations thereof herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless specified or limited otherwise, the terms “mounted,” “connected,” “supported,” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings. Further, “connected” and “coupled” are not restricted to physical or mechanical connections or couplings.

Unless otherwise specified or limited, phrases similar to “at least one of A, B, and C,” “one or more of A, B, and C,” and the like, are meant to indicate A, or B, or C, or any combination of A, B, and/or C, including combinations with multiple or single instances of A, B, and/or C.

The following discussion is presented to enable a person skilled in the art to make and use embodiments of the invention. Various modifications to the illustrated embodiments will be readily apparent to those skilled in the art, and the generic principles herein can be applied to other embodiments and applications without departing from embodiments of the invention. Thus, embodiments of the invention are not intended to be limited to embodiments shown, but are to be accorded the widest scope consistent with the principles and features disclosed herein. Skilled artisans will recognize the examples provided herein have many useful alternatives and fall within the scope of embodiments of the invention.

As used herein, the term “processor” and “controller” may include one or more processors and memories and/or one or more programmable hardware elements. As used herein, the term “processor” and “controller” is intended to include any of types of processors, CPUs, microcontrollers, digital signal processors, or other devices capable of executing software instructions.

As used herein, the terms “edge” and “aligned” may refer to the spatial relationship between one or more illumination regions. For example, an “edge” of an illumination region “aligned” with an “edge” on a different illumination region may refer to multiple configurations. A first configuration being the two edges are shared by the two illumination regions. A second configuration may include the two edges being parallel or perpendicular to each other. A third configuration may include a slight overlap between the two illumination regions, due to the imperfect nature of optical components and/or illumination sources (e.g., the optical performance of reflectors, lens, light emitting diodes (“LEDs”), etc., in practice is not theoretically-perfect so some overlap may occur), which can be understood by a person skilled in the art. A last configuration can be any combination thereof.

The various embodiments of the vehicle headlight system disclosed herein will be described in connection with a vehicle that leans during a turn (e.g., banking vehicles, leaning vehicles, etc.). Examples of these vehicles include, but are not limited to, saddle-ride vehicles, motorcycles, three-wheeled motor vehicles, snowmobiles, and ATVs (all-terrain vehicles). When turning, banking vehicles “lean” into a turn, rotating the entire vehicle towards the ground, generally due to the driver shifting their center of mass inducing torque on the vehicle. As will be described herein, the vehicle headlight systems and methods described may include features and advantages that are well suited for vehicles that lean, or bank, into turns.

The present disclosure provides various systems and methods for producing and/or controlling an illumination pattern that includes individual illumination regions. In accordance with various embodiments, the illumination pattern can be formed and/or adjusted, for example, to prevent shining light onto an oncoming vehicle. For example, the illumination pattern can be changed by selectively adjusting an illumination intensity of one or more of the illumination regions. In some embodiments, an indication may be provided that indicates a vehicles is rotating (e.g., from a sensor) and, in response, the individual illumination regions can be adjusted accordingly. In this way, for example, an intensity of one or more of the illumination regions that are directed toward an oncoming vehicle or object may be decreased. Additionally, an intensity of one or more of the illumination regions that aid in the drivers visibility can be increased. For example, as the illumination pattern rotates in response to a vehicle turn, one or more of the illumination regions on a side of the illumination pattern into which the vehicle is leaning may be sequentially increased as a function of the vehicle lean, while one or more of the illumination regions on an opposite side of the illumination pattern away from which the vehicle is leaning may be sequentially decreased as a function of the vehicle lean.

In some embodiments, the shape of the individual illumination regions on the sides of the illumination pattern can be advantageous to both decrease shining light on an oncoming vehicle, and increase visibility for the driver of the banking vehicle. For example, one or more of the illumination regions can be angled relative a horizontal optical axis and/or a vertical optical axis. The one or more angled illumination regions within the illumination pattern can have a corresponding illumination region symmetrically arranged about the vertical optical axis. The angled shape of the one or more illumination regions provides increased visibility on the side facing the turning side, and decreased visibility of the side opposite the turning side. For example, when the vehicle leans the angled illumination region(s) facing the leaning side, more closely follows the road, as the angled illumination region(s) align closer to becoming parallel with the road's surface, providing increased visibility to the driver. Additionally, when a vehicle leans the angled illumination region(s) opposite the leaning side, further deviates from the road, as the angled illumination region(s) align closer to becoming perpendicular to the road's surface and decrease light shining on oncoming traffic. In some embodiments, a vehicle input (e.g., a sensor) can quantify the degree of leaning during a turn. This vehicle input can be electrically connected to a controller that can adjust the intensity of the one or more angled illumination region(s) on the leaning side and/or the side opposite the leaning side.

As shown in FIG. 1, in some embodiments, the headlight system 100 can include a one or more of optical assemblies 102. In the illustrated embodiment, four optical assemblies 102 are illustrated. In some embodiments, the headlight system 100 may include more or less than four optical assemblies 102. In some embodiments, each optical assembly 102 can include an illumination source 104 and an optical element 106. In some embodiments, the illumination source 104 can include any device capable of emitting visible electromagnetic radiation (“light”). For example, the illumination source can include a light emitting diode (“LED”), an incandescent light bulb, a fluorescent lamp, etc. In some embodiments the illumination source 104 can include various LED patterns. For example, the illumination source 104 can include any suitable array of single or multi-die LEDs. As a further example, the illumination source 104 can include a 2-die by 11 LED array, or a 5-die by 2 LED array. In some embodiments, the optical element 104 can include any device capable of directing, diverging, converging and/or manipulating light in any manner. For example, the optical element 104 can include reflectors, lenses, mirrors, polarizers, waveplates, beamsplitters, prisms, filters, etc. As a further example, the optical element 104 can include any optical components as listed above or including others known in the art, capable of directing light in a particular pattern or shape.

In some embodiments, each illumination source 102 can emit light, and the emitted light can be directed by the corresponding optical element 104. The light directed by the corresponding optical element 104 can create an individual illumination region. As shown in FIG. 1, each optical assembly 102 forms its own individual illumination region (e.g., a first illumination region 108, a second illumination region 110, a third illumination region 112, and a fourth illumination region 114). Each illumination region can create a particular illumination shape. For example, the shape can include a square, rectangle, trapezoid, triangle, any polygon, etc. In some embodiments, each illumination region can have a generally uniform and distinct illumination intensity. For example, an illumination region can be a square with a distinct quantitative irradiance value throughout the area of the square. In some embodiments, the distinct quantitative irradiance value of the illumination region can be proportional to the intensity of the corresponding illumination source 104 within its optical assembly 102.

In some embodiments, the illumination regions combine to form an illumination pattern 116. In some embodiments, the illumination regions are individually controllable within the illumination pattern 116 (i.e., controlling one region generally may not affect another region). However, in practice, the optical performance of the optical assemblies 102 is not theoretically-perfect, so some overlap may occur between adjacent illumination regions within the illumination pattern 116.

In some embodiments, the headlight system 100 can include a controller 118 in communication with the optical assemblies 102. Specifically, in some embodiments, the controller 118 can be in communication with the illumination sources 104. The headlight system 100 can also include an input 120 in communication with the controller 118. The input 120 can include a sensor (e.g., an accelerometer, a gyroscope, a handlebar positional sensor etc.), and/or a vehicle input already configured (e.g., a wheel encoder, a brake indicator, etc.) configured to measure changes it its environment. In some embodiments, the input 120 may be configured to detect a vehicle or object within the illumination pattern 116, for example, via a camera or another imaging device.

In some embodiments, the controller 118 can receive a signal from the input 120 and adjust the illumination intensity of one or more of the illumination sources 104. In this way, for example, an intensity or brightness of one or more illumination regions may be adjusted, based on a signal from the input 120. As an example, the input 120 can be an accelerometer that measures the bank or lean of a vehicle. When a vehicle leans, the controller 118 can sense changes in the orientation of the vehicle based on a signal from the accelerometer and adjust the illumination intensity of one or more of the illumination sources 104. In some embodiments, the controller 118 may control the illumination sources 104 via pulse width modulation (PWM).

As shown in FIGS. 2 and 3, in some embodiments, the illumination pattern 116 can include a mesh of individual illumination regions. For example, as illustrated in FIGS. 2 and 3, illumination pattern 116 includes thirteen illumination regions each having its own controllable illumination output and corresponding illumination source 104. In some embodiments, the illumination pattern 116 may include more or less than thirteen illumination regions. The illumination pattern 116 can be arranged about an optical horizon 122 and an optical vertical axis 124. In the illustrated embodiment, the illumination pattern 116 can include a lower illumination region 126, a lower left illumination region 128, an upper-left illumination region 130, an upper illumination region 132, an upper-right illumination region 134, a lower right illumination region 136, and a center section 137. The center section 137 can include a left most center illumination region 138, a left center illumination region 140, three center illumination regions 142, 144, 146, a right illumination region 148, and a right most center illumination region 150. In some embodiments, the center section 137 can include more or less than three center illumination regions.

In the illustrated embodiment, the center section 137 can be positioned above the lower illumination region 126, and below the upper illumination region 132. In some embodiments, the center section 137 can be positioned right (from the perspective of FIGS. 2 and 3) of the lower left illumination region 126 and the upper-left illumination region 130. In some embodiments, the center section 137 can be positioned left (from the perspective of FIGS. 2 and 3) of the lower right illumination region 136 and the upper-right illumination region 134.

In the illustrated embodiment, the lower illumination region 126, the lower left illumination region 128, the upper-left illumination region 130, the upper-right illumination region 134, the lower right illumination region 136, the left most center illumination region 138, the left center illumination region 140, the right illumination region 148, and the right most center illumination region 150 may define a generally trapezoidal shape. In some embodiments, the lower illumination region 126, the lower left illumination region 128, the upper-left illumination region 130, the upper-right illumination region 134, the lower right illumination region 136, the left most center illumination region 138, the left center illumination region 140, the right illumination region 148, and/or the right most center illumination region 150 may define another shape, which may be designed to accommodate a specific vehicle or desired illumination pattern, for example, another polygon, triangular, pie-shaped, wedge-shaped, or rectangular. In the illustrated embodiment, the center illumination regions 142, 144, 146 can define a generally rectangular shape. In some embodiments, the center illumination regions 142, 144, 146 can define another shape, which may be designed to accommodate a specific vehicle or desired illumination pattern, for example, another polygon, triangular, pie-shaped, wedge-shaped, round, semi-circular, or circular.

In some embodiments, the illumination pattern may be symmetric about the optical vertical axis 146. For example, the left most center illumination region 138 and the right most center illumination region 150 can be symmetric about the optical vertical axis 124. The left center illumination region 140 and the right center illumination region 146 can be symmetric about the optical vertical axis 124. The central illumination region 142 and the central illumination region 146 can be symmetric about the optical vertical axis 124.

In the illustrated embodiment, the lower left illumination region 128 and the upper-left illumination region 130 may be symmetrical with the lower right illumination region 136 and the upper-right illumination region 134 about the vertical optical axis 124. Therefore, the following description of the lower left illumination region 128 and the upper-left illumination region 130 symmetrically applies to the lower right illumination region 136 and the upper-right illumination region 134. In the illustrated embodiment, the lower left illumination region 128 and the upper-left region 130 define laterally-elongated shapes, which extend from the center section 137 laterally outward (i.e., away from the vertical optical axis 124). The lower left illumination region 128 and the upper-left illumination region 130 are angled with respect to the optical horizon 122. That is, the laterally-extending borders, or edges, of the lower left illumination region 128 and the upper-left region 130 are angled with respect to the optical horizon 122. In other words, the laterally-extending borders, or edges, of the lower left illumination region 128 and the upper-left region 130 may, if extended, intercept the optical horizon 122 at a predefined angle. As will be described herein, the laterally-elongated shapes defined by the lower left illumination region 128 and the upper-left region 130 are advantageous for leaning vehicles.

FIG. 3 illustrates a quantitative view of the illumination pattern 116, where the boundaries of each illumination region are overlaid on a grid. The boundaries of each illumination region define edges, as discussed above, where the angles and relative length of the edges can be easily quantified based on their location on the grid. In the illustrated embodiment, the illumination pattern 116 may extend sixty degrees along the optical horizon 122 (i.e., thirty degrees in both directions from the optical vertical axis 124).

FIGS. 4 and 5 show multiple views of a headlight system 200, illustrating a particular embodiment of the headlight system 100. In some embodiments, the headlight system 200 can include an upper-right reflector 202, a lower right reflector 206, a lower central reflector 210, a lower left reflector 214, an upper-left reflector 218, and an upper central reflector 222. Each reflector 202, 206, 210, 214, 218, and 222 can have at least one reflector surface 204, 208, 212, 216, 220, and 222, respectively. In the illustrated embodiment, the reflector surfaces 204, 208, 212, 216, 220, and 222 may define a generally curved or arcuate shape to provide a predetermined shape in an illumination region.

Each reflector 202, 206, 210, 214, 218, and/or reflector surface 204, 208, 212, 216, 220, and 222, can have a corresponding illumination source 226 configured to direct light toward the respective reflector 202, 206, 210, 214, 218 and/or reflector surface 204, 208, 212, 216, 220, and 222. In some embodiments, each reflector surface (e.g., reflector surface 204) within its reflector (e.g., reflector 202) directs, or more specifically reflects, light from the corresponding illumination source 226 to produce an illumination region. In some embodiments, each reflector (e.g., reflector 202) can have more than one reflector surface (e.g., reflector surface 204), each reflector surface within the one or more reflector surfaces can direct, and more specifically reflect light, from the corresponding illumination source 226 within the reflector, to create multiple separate illumination regions based on each individual reflector surface. In some embodiments, the geometry of the reflector surface, the material of the reflector surface, the characteristics of the illumination sources 226, and/or the spatial relationship between the illumination source and the reflector surface can define a shape, size, and/or position of an illumination region. In some embodiments, each illumination source 226 can include a light emitting diode (“LED”), an incandescent light bulb, a fluorescent lamp, etc. In some embodiments the illumination sources 226 can include various LED patterns. For example, the illumination sources 226 can include any suitable array of single or multi-die LEDs. As another example, the illumination sources 226 can include a 1-die LED array, 2-die LED array, 3-die LED array, and/or 5-die LED array. As a further example, the illumination sources 226 can include a row of two, 3-die LEDs, a row of two, 5-die LEDs, and/or a row of two 1-die LEDs.

In some embodiments, each illumination source 226 can be in electrical communication with a controller (not shown), similar to the illumination sources 118 described herein. The controller can selectively adjust the illumination intensity of each illumination source 226, which an illumination intensity of the corresponding illumination region produced by the light reflected by the respective reflector. For example, by decreasing the illumination intensity of the illumination source 226 corresponding with the reflector surface 204, the illumination region produced only by the reflector surface 204 also decreases in illumination intensity, independently of the other illumination regions that also form an illumination pattern 228 (see. e.g., FIGS. 6 and 7). In some embodiments, the controller can also be in communication with an input (e.g., input 120). For example, the controller can receive a signal corresponding to a change in rotation, lean, or banking of a vehicle (e.g., the degree, speed, and/or direction of rotation). Based on the signal from the input, the controller can adjust one or more of the illumination sources 226 thereby adjusting the corresponding illumination region(s).

FIG. 6 shows a graph of an illumination pattern 228 produced using the headlight system 200. The illumination pattern 228 can be formed of individual illumination regions, where each illumination region can be adjusted independently from other illumination regions. FIG. 6 specifically shows the illumination intensity of the illumination pattern 228, by capturing the luminous flux distribution represented on a candela distribution graph.

FIGS. 7-9 show outlines of the individual illumination regions that form the illumination pattern 228. For example, the illumination pattern 228 can include a lower illumination region 250, a left-side illumination section 230, a right-side illumination section 231, a central illumination section 238, an upper-left illumination region 251, and an upper-right illumination region 252. In some embodiments, the central illumination section 238 can be generally arranged centrally relative the left-side illumination section 230 and the right-side illumination section 231. In some embodiments, the central illumination section 238 can be positioned above the lower illumination region 250 and below the upper-left illumination region 251 and the upper-right illumination region 252.

In some embodiments, the left-side illumination section 230 can include a first left-side illumination region 232, a second left-side illumination region 234, and a third left-side illumination region 236. In some embodiments, the second left-side illumination region 234 can be positioned above the third left-side illumination region 236 and below the first left-side illumination region 232. In some embodiments, the right-side illumination section 231 can include a first right-side illumination region 233, a second right-side illumination region 235, and a third right-side illumination region 237. In some embodiments, the second right-side illumination region 235 can be positioned above the third right-side illumination region 237 and below the first right-side illumination region 233.

In the illustrated embodiment, the left-side illumination section 230 and the right-side illumination section 231 may be symmetrical about the vertical axis. Therefore, the following description of the left-side illumination section 230 symmetrically applies to the right-side illumination section 231. In the illustrated embodiment, the first left-side illumination region 232, the second left-side illumination region 234, and the third left-side illumination region 236 can define laterally-elongated shapes, which extend from the central illumination section 238 laterally outward (i.e., away from the vertical axis). Each of the first left-side illumination region 232, the second left-side illumination region 234, and the third left-side illumination region 236 is angled with respect to the horizontal axis. That is, the laterally-extending borders, or edges, of the first left-side illumination region 232, the second left-side illumination region 234, and the third left-side illumination region 236 are angled with respect to the horizontal axis. In addition, the first left-side illumination region 232, the second left-side illumination region 234, and the third left-side illumination region 236 each extend a greater angular distance laterally (i.e., in a general horizontal direction) than vertically. As will be described herein, the laterally-elongated shapes defined by the first left-side illumination region 232, the second left-side illumination region 234, and the third left-side illumination region 236 are advantageous for leaning vehicles.

In the illustrated embodiment, the central illumination section 238 can include a first center illumination region 240, a second center illumination region 242, a third central illumination region 244, a fourth central illumination region 246, and a fifth central illumination region 248. The third central illumination region 244 can be placed centrally with respect to the other regions within the central illumination section 238 (e.g., centered with respect to the origin in the illumination pattern 228). In some embodiments, the third central illumination region 244 can be positioned between the second central illumination region 242 and the fourth central illumination region 246. In some embodiments, the third central illumination region 244 can be positioned between the first central illumination region 240 and the fifth central illumination region 248. In some embodiments, the first central illumination region 240 can be symmetrical with the fifth central illumination region 248, and/or the second central illumination region 242 can be symmetrical with the fourth central illumination region 246.

As illustrated in FIGS. 7-9, some of the illumination regions may overlap with other adjacent illumination regions. For example, in practice, the optical performance of the optical components (e.g., reflector 202, reflector surface 204, and/or illumination sources 226) within the headlight system 200 may not be theoretically-perfect. Thus, some overlap between adjacent illumination regions (e.g., a first side illumination region 232 and a second side illumination region 234) may occur within the illumination pattern 228. That being said, the control of an illumination source 228 for a given illumination region within the illumination pattern 228 may control a substantial portion of the illuminous flux within that illumination region. For example, the control of an illumination source 228 for a given illumination region may control greater than 50% of the illuminous flux within the illumination region, greater than 60% of the illuminous flux within the illumination region, greater than 70% of the illuminous flux within the illumination region, greater than 80% of the illuminous flux within the illumination region, or greater than 90% of the illuminous flux within the illumination region. Thus, while some overlap may occur, the headlight system 200 is configured to output of generally discretized illumination regions via the use of a plurality of illumination sources 226 each configured to direct light toward a respective one of the reflectors 202, 206, 210, 214, 218. The use of illumination sources 226 (e.g., LED(s)) and reflectors 202, 206, 210, 214, 218 provides a low-cost solution to providing individually-controllable, generally discrete illumination regions within an illumination pattern, for example, compared to a projector-based solution.

As discussed above generally, each illumination region (e.g., the first side illumination region 232) can have an illumination intensity generally independent of other illumination regions. Each illumination region (e.g., the first side illumination region 232) can be created from a corresponding illumination source (e.g., illumination source 226) that emits light and a corresponding reflector (e.g., reflector 206) and/or a reflector surface (e.g., reflector surface 208) that reflects the emitted light creating each illumination region. Thus, different reflectors, reflector surfaces, and/or illumination sources within the headlight system 200 create each individual illumination region. As detailed above, each illumination source 226 that corresponds to a respective illumination region can be adjusted, as to increase or decrease the illumination of each illumination region accordingly. For example, when a vehicle on which the headlight system 200 is mounted rotates (i.e., banks or leans) in a first direction (e.g., rotates in a counterclockwise direction from the perspective of FIGS. 7-9) during a turn, a vehicle input senses the turn and inputs a signal to the controller that is proportional to the amount of banking or lean experience by the vehicle. In response to the input, the controller (e.g., controller 118) may increase the illumination intensities of the first left-side illumination region 232, the second left-side illumination region 234, and/or the third left-side illumination region 236 by increasing the illumination of the corresponding illumination sources 226 (e.g., increasing a duty cycle of a PWM signal applied to the illumination source 226 corresponding illumination regions). In addition, the controller may decrease the illumination intensities of the first right-side illumination region 231, the second right-side illumination region 233, and/or the third right-side illumination region 235.

As a further example, the controller can increase the intensities of the side illumination regions that are positioned closer to the horizontal axis first, compared to the side regions positioned farther away from the horizontal axis. For example, as the vehicle first begins to turn, or as a function of the vehicle's lean/bank angle of rotation in a counterclockwise direction (from the perspective of FIGS. 7-9), the controller may increase the illumination intensity of the third left-side illumination region 236, before increasing the intensity of the second left-side illumination region 234 and/or the first left-side illumination region 232. Similarly, and substantially simultaneously, as the vehicle begins to turn in a counterclockwise direction, the controller can decrease the illumination intensity of the first right-side illumination region 233 before decreasing the illumination intensity of the second right-side illumination region 235 and/or the first right-side illumination region 233. These controlled variations in the selected illumination regions and the laterally-extending shapes of the illumination regions within the left-side illumination section 230 and the right-side illumination section 231 can advantageously allow the illumination regions that contour the road to be further illuminated in a sequential manner during a turn. In addition, the illumination regions that deviate from the road (e.g., toward an oncoming vehicle or object, or away from the road on which the vehicle is traveling) may be substantially simultaneously decreased in illumination. In some embodiments, the illumination adjustment of specific regions can be reversed and/or opposite as discussed with regard to counterclockwise rotation. For example, when the vehicle and illumination pattern 228 rotates in a clockwise direction, the third right-side illumination region 237 may initially increase in illumination intensity, while the first side illumination region 232 may initially decrease in illumination intensity.

In some embodiments, the lower right reflector 206 can include the reflector surface 208. In some embodiments, the reflector surface 208 may include one or more reflector panels the comprise the reflector surface 208. The reflector surface 208 can include specific geometric, material properties (e.g., curvatures), and can include a corresponding one of the illumination sources 226 positioned to direct light toward the reflector surface 208. The light reflected from the reflector surface 208 may produce a corresponding illumination region.

FIG. 14 illustrates a spatial view of the upper central reflector 222. In some embodiments, the upper central reflector 222 can include the reflector surface 224. In some embodiments, the reflector surface 224 can include one or more reflector panels that comprise the reflector surface 224. The reflector surface 224 can include specific geometric, material properties (e.g., curvatures), and can include a corresponding one of the illumination sources 226 positioned to direct light toward the reflector surface 224. The light reflected from the reflector surface 224 may produce a corresponding illumination region.

In some embodiments, the upper central reflector 222 includes a corresponding illumination source 226 that produces the lower illumination region 250.

FIGS. 18 and 19 show multiple views of a headlight system 300, illustrating a particular embodiment of the headlight system 100. In some embodiments, the headlight system 300 can include a first left-side lens 302, a second left-side lens 306, a third left-side lens 312, a fourth left-side lens 314, and a fifth left-side lens 318, an upper central lens 322, a central lens 326, a lower central lens 330, a first right-side lens 334, a second right-side lens 338, a third right-side lens 342, a fourth right-side lens 346, and a fifth right-side lens 350. Each lens 302, 306, 310, 341, 318, 322, 326, 330, 334, 338, 342, 346, and 350 can have at least one lens surface 304, 308, 312, 316, 320, 324, 328, 332, 336, 340, 344, 348, and 351, respectively. In some embodiments, each lens 302, 306, 310, 341, 318, 322, 326, 330, 334, 338, 342, 346, 350 and/or lens surface 304, 308, 312, 316, 320, 324, 328, 332, 336, 340, 344, 348, and 351, can have a corresponding illumination source 352. In some embodiments, each lens surface within its lens directs, or shapes, light from the corresponding illumination source 352 to produce an illumination region having a selectively controllable illumination intensity. In some embodiments, the geometry of the lens surface, the material of the lens surface, the characteristics of the illumination source 352, and/or the spatial relationship between the illumination source and the lens can define a shape, size, and/or position of an illumination region. In some embodiments, each illumination source 352 can include a light emitting diode (“LED”), an incandescent light bulb, a fluorescent lamp, etc. In some embodiments the illumination sources 352 can include various LED patterns. For example, the illumination sources 352 can include any suitable array of single or multi-die LEDs. As a further example, the illumination sources 352 can include five, 2-die LEDs, positioned in a row. As another example, the illumination sources 352 can include a 5-die LED array and/or a 2-die LED array. As a further example, the illumination sources 352 can include eleven, 2-die LEDs, positioned in a row, and/or two 5-die LEDs, positioned in a row.

In some embodiments, each illumination source 352 can be in electrical communication with a controller (not shown), similar to the illumination sources 118 described herein. The controller can selectively adjust the illumination intensity of each illumination source 352, which an illumination intensity of the corresponding illumination region produced by the light directed through a respective lens. For example, by decreasing the illumination intensity of the illumination source 352 corresponding with the lens surface 336, the illumination region produced only by the lens surface 336 also decreases in illumination intensity, independently of the other illumination regions that also form an illumination pattern 354 (see. e.g., FIGS. 20-23). In some embodiments, the controller can also be in communication with an input (e.g., input 120). For example, the controller can receive a signal corresponding to a change in rotation, lean, or banking of a vehicle (e.g., the degree, speed, and/or direction of rotation). Based on the signal from the input, the controller can adjust one or more of the illumination sources 352 thereby adjusting the corresponding illumination region(s).

FIG. 20 shows a graph of an illumination pattern 354 produced using the headlight system 300. The lens illumination pattern 354 can be formed of individual illumination regions, where each illumination region can be adjusted independently from other illumination zone regions. FIG. 20 specifically shows the illumination intensity of the lens illumination pattern 354 by capturing the luminous flux distribution represented on a candela distribution graph.

FIGS. 21-23 show outlines of the individual illumination regions that form the lens illumination pattern 354. For example, the lens illumination pattern 354 can include a lower illumination region 356, a left-side illumination section 367, a right-side illumination section 379, an upper illumination region 368, and a central illumination section 380. In some embodiments, the central illumination section 380 can be generally arranged centrally, relative the left-side illumination section 367 and the right-side illumination section 368. In some embodiments, the central illumination section 380 can be positioned above the lower illumination region 356 and below the upper illumination region 368. In some embodiments, the left-side illumination section 367 can include a first left-side illumination region 358, a second left-side illumination region 360, a third left-side illumination region 362, a fourth left-side illumination region 364, and a fifth left-side illumination region 366, all of which can be angled relative an optical horizon (e.g., a horizontal axis on the candela distribution graph). In the illustrated embodiment, the regions 358, 360, 362, 364, 366 within the left-side illumination section 367 can be in a fan-like arrangement. That is, the regions 358, 360, 362, 364, 366 may be circumferentially rotated or spaced with the first left-side illumination region 358 being arranged circumferentially below the second left-side illumination region 360, and so on.

In some embodiments, the right-side illumination section 379 can include a first right-side illumination region 370, a second right-side illumination region 372, a third right-side illumination region 374, a fourth right-side illumination region 376, and a fifth right-side illumination region 378, all of which can be angled relative an optical horizon (e.g., a horizontal axis on the candela distribution graph). In the illustrated embodiment, the regions 370, 372, 374, 376, 378 within the right-side illumination section 379 can be in a fan-like arrangement. That is, the regions 370, 372, 374, 376, 378 may be circumferentially rotated or spaced with the first right-side illumination region 378 being arranged circumferentially below the second right-side illumination region 376, and so on.

In the illustrated embodiment, the left-side illumination section 367 may be symmetrical to the right-side illumination section 379 about the vertical axis. Therefore, the following description of the left-side illumination section 367 symmetrically applies to the right-side illumination section 379. In the illustrated embodiment, the first left-side illumination region 358, the second left-side illumination region 360, the third left-side illumination region 362, the fourth left-side illumination region 364, and the fifth left-side illumination region 366 can define laterally-elongated shapes, which extend from the central illumination section 380 laterally outward (i.e., away from the vertical axis). Each of the first left-side illumination region 358, the second left-side illumination region 360, the third left-side illumination region 362, the fourth left-side illumination region 364, and the fifth left-side illumination region 366 is angled with respect to the horizontal axis. That is, the laterally-extending borders, or edges, of the first left-side illumination region 358, the second left-side illumination region 360, the third left-side illumination region 362, the fourth left-side illumination region 364, and the fifth left-side illumination region 366 are angled with respect to the horizontal axis. In addition, the first left-side illumination region 358, the second left-side illumination region 360, the third left-side illumination region 362, the fourth left-side illumination region 364, and the fifth left-side illumination region 366 extend a greater angular distance laterally (i.e., in a general horizontal direction) than vertically. As will be described herein the laterally-elongated shapes defined by the first left-side illumination region 358, the second left-side illumination region 360, the third left-side illumination region 362, the fourth left-side illumination region 364, and the fifth left-side illumination region 366 are advantageous for leaning vehicles.

In some embodiments, the central illumination section 380 can include a left most central illumination region 382, a left central illumination region 384, a central illumination region 386, a right central illumination region 388, and a right most central illumination region 390. The central illumination region 386 can be placed centrally with respect to the other regions within the central illumination pattern 380. In some embodiments, the central illumination region 386 defines an optical origin for the illumination pattern 354. In some embodiments, the central illumination region 386 can be positioned between the left most central illumination region 382 and the right most central illumination region 390. In some embodiments, the central illumination region 386 can be positioned between the left central illumination region 384 and the right central illumination region 388. In some embodiments, the upper illumination region 368 can overlap with any illumination regions within the central illumination section 380, the left-side illumination section 367, and/or the right-side illumination section 379.

As illustrated in FIGS. 21-23, some of the illumination regions overlap with other illumination regions. For example, in practice, the optical performance of the optical components (e.g., lens 302, lens surface 304, and/or illumination sources 352) within the headlight system 300 may not be theoretically-perfect. Thus, some overlap between adjacent illumination regions (e.g., the first left-side illumination region 358 and the second left-side illumination region 360) may occur within the lens illumination pattern 354. That being said, the control of an illumination source 352 for a given illumination region with in the illumination pattern 354 may control a substantial portion of the illuminous flux within the illumination region. For example, the control of an illumination source 352 for a given illumination region may control greater than 50% of the illuminous flux within the illumination region, greater than 60% of the illuminous flux within the illumination region, greater than 70% of the illuminous flux within the illumination region, greater than 80% of the illuminous flux within the illumination region, or greater than 90% of the illuminous flux within the illumination region. Thus, while some overlap may occur, the headlight system 300 is configured to output of generally discretized illumination regions via the use of a plurality of illumination sources 352 each configured to direct light toward a respective one of the lens 302, 306, 310, 341, 318, 322, 326, 330, 334, 338, 342, 346, 350. The use of illumination sources 354 (e.g., LED(s)) and lens 302, 306, 310, 341, 318, 322, 326, 330, 334, 338, 342, 346, 350 provides a lost-cost solution to providing individually-controllable, generally discrete illumination regions within an illumination pattern, for example, compared to a projector-based solution.

As discussed above generally, each illumination region (e.g., the first left-side illumination region 358) can have an illumination intensity generally independent of other illumination regions. Each illumination region (e.g., the lower illumination region 356) can be created from a corresponding illumination source (e.g., illumination source 356) that emits light and a corresponding reflector (e.g., lens 332) and/or a lens surface (e.g., lens surface 324) that directs the emitted light creating each illumination region. Thus, different lenses, lens surfaces, and/or illumination sources within the headlight system 300 create each individual illumination region. As detailed above, each illumination source 356 that corresponds to a respective illumination region can be adjusted, as to increase or decrease the illumination of each illumination region accordingly. For example, when a vehicle on which the headlight system 300 is mounted rotates (i.e., banks or leans) during a turn in a first direction (e.g., rotates in a counterclockwise direction from the perspective of FIGS. 20-23), a vehicle input senses the turn and inputs a signal to the controller that is proportional to the amount of banking or lean experience by the vehicle. In response to the input, a controller (e.g., controller 118) may increase the illumination intensities of the first left-side illumination region 358, the second left-side illumination region 360, the third left-side illumination region 362, the fourth left-side illumination region 364, and/or the fifth left-side illumination region 366 by increasing the illumination of the corresponding illumination sources 352 (e.g., increasing a duty cycle of a PWN signal applied to the illumination source 352 corresponding illumination regions). In addition, the controller may decrease the illumination intensities of the first right-side illumination region 370, the second right-side illumination region 372, the third right-side illumination region 374, the fourth right-side illumination region 376, and/or the fifth right-side illumination region 378.

As a further example, the controller can increase the intensities of the side illumination regions that are positioned closer to the optical horizon first, compared to the side regions positioned farther away from the optical horizon. For example, as the vehicle first begins to turn, or as a function of the vehicle's lean/bank angle of rotation in a counterclockwise direction (from the perspective of FIGS. 20-23), the controller may increase the illumination intensity of the first left-side illumination region 358 before increasing the intensity of the remaining left-side illumination regions 360-366. Similarly, and substantially simultaneously, as the vehicle begins to turn in a counterclockwise direction, the controller can decrease the illumination intensity of the fifth right-side illumination region 378, before decreasing the illumination intensity of the other remaining right-side illumination regions 372-378. These controlled variations in the selected illumination regions and the laterally-extending shapes of the illumination regions within the left-side section 367 and the right-side section 379 can allow the illumination regions that contour the road to be further illuminated in a sequential manner during a turn. In addition, the illumination regions that deviate from the road (e.g., toward an oncoming vehicle or object, or away from the road on which the vehicle is traveling) may be substantially simultaneously decreased in illumination. In some embodiments, the illumination adjustment of specific regions can be reversed and/or opposite as discussed with regard to counterclockwise rotation. For example, when the vehicle and illumination pattern 354 rotates in a clockwise direction, the first right-side illumination region 370 may initially increase in illumination intensity, while the fifth left-side illumination region 366 may initially decrease in illumination intensity.

FIG. 24 illustrates the first left-side lens 302, the second left-side lens 306, the third left-side lens 312, the fourth left-side lens 314, and the fifth left-side lens 318. In some embodiments, each left-side lens within the group of left-side lenses (e.g., a first left-side lens 302) can include one or more lens surfaces (e.g., one or more lens surfaces 304). Each lens can include specific geometric, material properties (e.g., curvatures), and can include one or more illumination sources (e.g., illumination source 352) positioned to direct light toward the lens surface. The light directed through the lens surface may produce a corresponding illumination region.

FIGS. 25A-25F illustrate candela distribution graphs for the right-side illumination section 379, and each of the illumination regions within the left-side illumination section 367. In some embodiments, each of the left-side lenses can include an illumination source 352 that corresponds with a lens surface 336, 340, 344, 348, 352 within each of the right-side lenses 334, 338, 342, 346, 350 to produce individual illumination regions. In some embodiments, an illumination source 352 associated with each of the first right-side lens 334, the second right-side lens 338, the third right-side lens 342, the fourth right-side lens 346, and the fifth right-side lens 350 produces the fifth left-side illumination region 378, the fourth right-side illumination region 376, the third right-side illumination region 374, the fourth right-side illumination region 372, and the first right-side illumination region 370, respectively. FIG. 25B illustrates a candela distribution graph of the fifth right-side illumination region 378, FIG. 25C illustrates a candela distribution graph of the fourth right-side illumination region 376, FIG. 25D illustrates a candela distribution graph of the third right-side illumination region 374, FIG. 25E illustrates a candela distribution graph of the second right-side illumination region 372, and FIG. 25F illustrates a candela distribution graph of the first right-side illumination region 370.

In some embodiments, each of the left-side lenses can include an illumination source 352 that corresponds with a lens surface 304, 308, 312, 316, 320 within each of the left-side lenses 302, 306, 310, 314, 318 to produce individual illumination regions. In some embodiments, an illumination source 352 associated with each of the first left-side lens 302, the second left-side lens 306, the third left-side lens 310, the fourth left-side lens 314, and the fifth left-side lens 318 produces the first left-side illumination region 358, the second left-side illumination region 360, the third left-side illumination region 362, the fourth left-side illumination region 364, and the fifth left-side illumination region 366, respectively.

FIG. 26 illustrates a spatial view of the lower central lens 330. In some embodiments, the lower central lens 330 can include the lens surface 332. The lens surface 332 can include specific geometric, material properties (e.g., curvatures), and can include a corresponding one of the illumination sources 352 positioned to direct light toward the lens surface 332. The light directed by the lens surface 332 may produce a corresponding illumination region.

FIGS. 27A-27F illustrate candela distribution graphs for the central illumination section 380, and each of the illumination regions within the central illumination section 380.
